Change subject: ipwrapper.addrFlush: flush only globally routable addresses
......................................................................


Patch Set 5: Verified+1

On a veth pair with dnsmasq (acting as a DHCPv6 server) I tried these pure IPv6 cases:

1) vdsClient -s 0 setupNetworks networks='{test-addrflush:{nic:veth1,bridged:false,dhcpv6:true}}' on a freshly set-up veth pair (so veth1 already had an IPv6 link-local address)

After removing the network (and the dynamically acquired IPv6 address) the link-local address was preserved so another testing round was possible.

2) Takeover from an existing dhclient -6 using the same command. A foreign dhclient -6 was killed and replaced by VDSM's own and it successfully obtained an address.

vdsClient -s 0 setupNetworks networks='{test-addrflush:{remove:true}}' left the link-local address intact.
